Overview

This document provides detailed technical specifications, dimensions, accessories, and operational characteristics for a range of changeover switches compliant with IEC 60947-3 standards. The switches are designed for base mounting in 3-pole (3P) and 3-pole plus neutral (3P+N) configurations, covering rated currents from 200A up to 1250A.

Product Series and Models

The changeover switches are categorized by current ratings and sizes:

• Size 1: 200A, 250A, 315A, 400A
• Size 2: 500A, 630A, 800A
• Size 3: 1000A, 1250A

Each size includes models with different pole configurations (3P and 3P+N) and types (CCF and CCP).

Electrical Ratings and Performance

• Rated Thermal Current (Ith): Ranges from 200A to 1250A depending on size.
• Rated Insulation Voltage (Ui): 1000 V across all models.
• Rated Impulse Withstand Voltage (Uimp): 8 kV for sizes 1, 12 kV for sizes 2 and 3.
• Rated Operational Current (Ie) at 400V AC: Matches the thermal current rating for AC21A and AC22B utilization categories.
• Rated Breaking and Making Capacity (AC22): Varies by size, e.g., 600-1200 A for size 1, 1500-2400 A for size 2, and 3000-3750 A for size 3.
• Short-Circuit Making Capacity (Icm): 12 kA peak for size 1, 20 kA for size 2, and 32 kA for size 3.
• Short-Time Withstand Current (Icw) 1 sec: 8 kA rms for size 1, 13 kA rms for size 2, and 25 kA rms for size 3.
• Mechanical Operations: Between 3000 and 8000 cycles depending on size and model.

Mechanical and Dimensional Data

• Dimensions and mounting details are provided for door drilling for external handles and key lock devices.
• Terminal shrouds and rear protective plates are available for 3P and 4P configurations.
• Shafts and shaft extensions are included or available as accessories, with detailed length and pitch dimensions.
• Maximum conductor cross-section (Cu) and terminal screw sizes (M) are specified per model.
• Weights vary by size and model, ranging from approximately 4.8 kg to 29.7 kg.

Accessories and Options

• Auxiliary Contacts: 1NO+1NC (Code D5LAU01) and 2NO+2NC (Code D5LAU02), rated 16 A resistive and 4 A inductive at 250 Vac.
• Safety Key Lock Devices: Simple and double versions available to lock the handle in OFF position (or ON on request), with key removal only possible when locked.
• Handles: Direct handle (Code DCCLIxx) and external handle with shaft included (IP65 rated, Code DCCLAxx).
• Terminal Shrouds and Rear Protective Plates: Various codes for 3P and 4P versions to enhance safety and installation flexibility.

Special Versions and Notes

• Versions without OFF (0) position are available, featuring overlapped contacts (CCF I - I+II - II), designated as CCS series; consultation required.
• 4-pole changeover switches are available upon request.
• Short-circuit ratings are given without limiting protective devices, assuming short-circuit duration between 50 ms and 100 ms.
• For other voltages or utilization categories, consultation with the manufacturer is recommended.

Standards Compliance

All changeover switches comply with IEC 60947-3, ensuring adherence to international standards for low-voltage switchgear and controlgear.

Summary
